There’s a common conundrum when you end a horror movie. When the credits roll, you have two choices, each with its pros and cons. You can make sure the villain is totally defeated and meets their mortal fate, which provides a satisfying ending for the characters who spent the last 100 minutes or so trying to survive, but cuts off any possibility of future movies.
Or, you can have a last-second tease that the villain somehow survived, which means you can revisit everything in a future movie and expand into a franchise, but it can be frustrating, especially if no future films ever manifest.
